Pomegranate Juice: Tart, Trendy, And Targeted On Prostate Cancer Cells

Pomegranate is an Iranian ancient fruit. Iran is the biggest producer of pomegranate in the world. most of Iranian pomegranate are natural and gardener produce pomegranate without any chemical fertilize and pesticide. an important things about Iranian pomegranate is the high diversity in the variety of this fruit. we have lots of variety of pomegranate with different taste.

In a new study, Navindra Seeram and colleagues have found that the tart, trendy beverage also uses a search-and-destroy strategy to target prostate cancer cells.In previous research, Seeram’s group found that pomegranate juice consumption had a beneficial effect for prostate cancer patients with rising prostate-specific antigen (PSA) levels. Such increases in PSA signal that the cancer is progressing, “doubling time” a key indicator of prognosis. Men whose PSA levels double in a short period are more likely to die from their cancer. Pomegranate juice increased doubling times by almost fourfold.

In the new study, they researchers discovered evidence in laboratory experiments that pomegranate works in a “seek and destroy” fashion. On consumption, ellagitannins (ET), antioxidants abundant in pomegranate juice, break down to metabolites known as urolithins. The researchers showed that the urolithins concentrate at high levels in prostate tissue after being given orally and by injection to mice with prostate cancer. They also showed that urolithins inhibited the growth of human prostate cancer cells in cell culture.

“The chemopreventive potential of pomegranate ellagitannins and localization of their bioactive metabolites in mouse prostate tissue suggest that pomegranate may play a role in prostate cancer treatment and chemoprevention,” the researchers state, recommending further clinical studies with pomegranate and prostate cancer patients.

This research, “Pomegranate Ellagitannin-Derived Metabolites Inhibit Prostate Cancer Growth and Localize to the Mouse Prostate Gland,” is scheduled for publication in the Sept. 19 issue of ACS’ Journal of Agricultural and Food Chemistry.

  1. Hi,

    Prosate cancer is very dangrous …

    I search lot of sites .. such as http://prostatecancersymptoms.info

    See it , it contain useful data and tips 🙂

  2. An alternative treatment that has become popular is saw palmetto. Saw palmetto, however, was recently found to have no effect in reducing the frequent urge to urinate or other annoying symptoms of an enlarged prostate. Published in the Feb. 9, 2006, New England Journal of Medicine, a yearlong study found that the plant extract was no more effective than inactive pills (placebos) in easing symptoms of BPH.

  3. One of the fastest emerging alternatives is HIFU, it actually destroys the prostate via ultrasound waves. Should be interesting to see what happens when this is approved.
